            Bug ID: 196138
           Summary: Unbound fails with 2(SERVFAIL) when behind NAT
           Product: Base System
           Version: 10.1-RELEASE
          Hardware: amd64
                OS: Any
            Status: New
          Severity: Affects Only Me
          Priority: ---
         Component: bin
          Assignee: freebsd-bugs at FreeBSD.org
          Reporter: rsimmons0 at gmail.com

I have tried this two different ways, one with my home router's DNS
(192.168.1.1), local_unbound fails. I also tried to set the default DNS server
to 8.8.8.8 which I know I can connect to, but local_unbound fails there as
well. Here is the output for setup that I followed. This is a fresh 10.1
install with freebsd-update already run.
